Leber's congenital amaurosis

I have a friend with Leber's born blind.he developed cataracts and  light perception until recently. he has almost none now. The last exam detected coloboma and that his retinas have died due to the cataracts. He suffers from the worst eye pain. so severe!
Is there any thing that can be done to relive the eye pain?
